The Yocan Uni Pro is the much anticipated update on the blockbuster Yocan Uni cartridge battery mod. You still have the revolutionary variable diameter adjustment to fit almost any cartridge out there as well as the height adjustment allowing you to easily use different capacity cartridges. The tried and true 510 Thread Magnetic Connector Ring is back ensuring compatibility with almost any 510 thread cartridge. The Uni Pro now has a beautiful OLED display that allows you to adjust the voltage between 2.0V and 4.2V in 0.1V increments! The Uni was easily our favorite cartridge vape with its innovative features, but the Uni Pro really blows it out of the water. There is really no point in using more words. The Uni Pro is so far our pick for the best cartridge battery mod of 2019!
